Subject: [PATCH 5634/5725] drm/amdkfd: remove check for PCIe upstream bridge
atomic support for GFX9 GPUs.
1. set vega10 needs_pci_atomics as false because vega10 do not need
pci atomics;
2. firstly try to enable atomics in pci_enable_atomic_ops_to_root()
and if this function failed and need_pic_atomics is true,
we need to report the error and return NULL.
